Which transfer of energy occurs when ice cubes are placed in water that has a temperature of 45^circ C Chemical energy is transferred from the ice to the water. Chemical energy is transferred from the water to the ice. Thermal energy is transferred from the ice to the water. C Thermal energy is traffisferred from the water to the ice.

1. When ice cubes are placed in water at a temperature of , thermal energy is transferred from the water to the ice. This is because heat flows from a warmer object (the water) to a cooler one (the ice) until thermal equilibrium is reached.2. The symbol stands for the change in enthalpy of a reaction. Enthalpy ( ) is a measure of the total energy of a thermodynamic system, and represents the difference in enthalpy between the products and reactants in a chemical reaction.
